Windham Weaponery R16M4TT AR-15. It shoots both the .223 and the 5.56mm round. It comes with Windham's lifetime transferable warranty and a plastic carrying case. It has one 30-round clip with the gun. It has never been fired. I'm willing to let it go to help fund a new project. Checked with Buds Guns website to set my price. 1500.00
